While researching a topic, a student has taken the following notes:
- Generally, an object will heat up when twisted.
- The twisting of an object is known as torsion.
- A 2019 study led by Zunfeng Liu and Ray Baughman tested the torsional heating of various fibers.
- When a sample of ethylene propylene diene monomer (EPDM) rubber fiber was twisted, its average surface temperature increased by 12°C.
- When a sample of four-ply nickel-titanium (NiTi) wire was twisted, its average surface temperature increased by 30.4°C.
The student wants to emphasize a similarity between EPDM rubber and four-ply NiTi wire fibers. Which choice most effectively uses relevant information from the notes to accomplish this goal?
In 2019, two research teams observed the effects of torsional heating on various fibers, including EPDM rubber and four-ply NiTi wire.
A
Both EPDM rubber and four-ply NiTi wire fibers heat up when twisted, according to a 2019 study.
B
Researchers determined that when the fibers were twisted, the average surface temperature of four-ply NiTi wire increased more than that of EPDM rubber.
C
Twisting an object will generally cause its temperature to increase, a process known as torsional heating.
D
